I did download those models and they seem to run for me without errors in 2022R1 and 2023R1. I was running on Windows, and I think you mentioned that you were using Linux. I've asked a colleague to check this on Linux for me. I'll let you know if that shows anything different. 
Just to check, are you able to try this on our latest 2023R1 release?
